This might just be the most flexible, powerful wah pedal ever. Designed in conjunction with legendary guitarist Dimebag Darrell, the DB01 Cry Baby From Hell features an extended sweep range with a fine tune knob, 6-way range selector, kick-in volume boost and LED indicators (Wah on/off, Boost on/off) at the back of the pedal. This hot-rodded pedal gives you everything you need to do serious wah damage.

Very user friendly. But like it's that hard to turn a knob or kick in a switch. Great sweep love the volume boost to 17 db love the griptape. there's nothing wrong with this pedal atleast that's what I think
